Great article explaining WELL's Biophilia I credit and how it pertains to lighting.   If you haven't read the full WELL Building Standard yet, I highly recommend you take a look.  Reading through the 102 features of the WELL, in essence, Feature 54 Circadian Light Design relates to pattern and Dynamic & Diffuse Light.  It provides the science behind the benefits of quality of light and discusses an alternate metric, Equivalent Menalopic Lux (EML), as a measurement of the effects of light on the circadian cycle.  

This can be seen in one of our most recent projects The Heights. This is a perfect example of how bringing light indoors, that mimics the sun can enhance feelings of wellness and increase productivity in an office environment.
